This is a list of Belgian football transfers for the 2018 summer transfer window.
Only transfers involving a team from the professional divisions are listed, including the 16 teams in the Belgian First Division A and the 8 teams playing in the Belgian First Division B.
The summer transfer window will open on 1 July 2018, although several transfers will be announced prior to that date.
Players without a club may join one at any time, either during or in between transfer windows.
The transfer window ends on 1 September 2018, although a few completed transfers could still be announced a few days later.
After the end of the 2017–18 season, several players will return from loan to another club or will not have their contracts extended.
